Perhaps you should try some spelling variations:
solutions algorithms » solution algorithm, evolution algorithm, convolution algorithms
near approximation » one approximation, network approximation, _ approximation
model solutions » nodal solution, global solutions
modified model » modified male
modified near » modified seird, modified adam

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified model solutions algorithms ) OR ( modified near approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified model solutions algorithms ) or ( modified near approximation algorithms ))*.
